About Me

Hi, I'm Tanjid Ahmed — though most people in the crypto space know me as xJupitar. I'm based in Dhaka, Bangladesh, and since graduating from the University of Dhaka in 2018, I've been all-in on blockchain and crypto.


With 7+ years of experience, I've worked across some of the most exciting corners of Web3 — building communities, running validator nodes, and helping projects grow from the ground up. Right now, I moderate for Citrea, Privasea, Tanari, and AgntHub, where I help drive engagement and keep communities thriving. In the past, I've worked with RetroBridge, UnlockFi, and NuLink, where I leveled up from moderator to manager and learned what it really takes to keep a community active and inspired.


On the technical side, I've operated validator nodes for networks like Redbelly and Powerloom, and previously for Sui, Celestia, Taiko, Opside, Ironfish, Massa, Q Blockchain, and Shardeum. That mix of community + infra work has given me a pretty unique perspective on both people and protocols.


I'm always excited to connect with fellow crypto enthusiasts and work on cool projects that are pushing the boundaries of what's possible with decentralized tech.
